It's recognized by the Austrian Medical Association. They recently put out a document trying to alert doctors on it and how to identify it. The World Health Organization in 2004 held a conference on electrical hypersensitivity. That's what they called it, but they decided that a better name for it would be idiopathic environmental illness. As “idiopathic” means that we don't have a clue as to what's causing it, this meant that they didn't have to do anything about it. There was a lot of debate on that and a lot of disagreement among the scientists. It just means that you don't have to deal with the problem, because you assume that you don't understand what it is.
It is recognized in parts of Europe. It's recognized by certain associations within the United States. The American Academy of Environmental Medicine is one of the groups that recognizes electrohypersensitivity along with multiple chemical sensitivity.
